Yeah, that's a weird chipset. Unless there's some accelerated driver
for it, you're kinda stuck. I suppose you could reduce the depth of
the viewport from 24 to 16 or something, but that reduces your color
rendering, and generally the vesa driver isn't truly horrible. Perhaps
there's something else, such as the shared memory segment being slow
or you're swapping a lot.
Have you tried googling for the PCI ID of the chipset? Perhaps there's
another driver out there that can work with it even if your X doesn't
recognize it due to its newness. In that case you can force X to use
the new driver anyway.
